| 摘 要： | 该文提出一种带有紧凑型电磁带隙结构的短路微带天线，并与相同尺寸的普通短路微带天线作比较。测试结果表明该电磁带隙结构天线在增益上增加了3dB， 面的交叉极化有了明显的改善。同时也证明了设计具有同样谐振频率的电磁带隙结构单元，使用这种紧凑型结构的单元边长尺寸仅为普通结构的5060％左右。这对最终实现电磁带隙结构微带相控阵天线具有重要意义。

| Abstract: | A micro-strip shorted antenna with Compact Electromagnetic Band-Gap structure (CEBG) is presented. A shorted antenna with identical dimensions on a conventional ground plane is also included, so that a direct performance comparison can be made. Measured data shows a gain improvement of 3dB and a significant reduction in cross polarization for the CEBG antenna. Meanwhile it also proves that to design the same resonant frequency, the CEBG structure cell size is only about 5060% of conventional structure, and this is significant in realizing EBG micro-strip phased antenna array. |
